APPARATUS FOR PRODUCING BURNT-WOOD ARTICLES.

To all whom it may concern:

Be it known that I, FRANK G. McALPIN, a citizen of the United States,residing at Forreston, in the county of Ogle and State of Illinois, haveinvented certain new and useful Improvements in Apparatus for ProducingBurnt-Wood Articles, of which the following is a specification.

The object of this invention is to mechanically produce burnt woodarticles, and consists in the employment of a suitably engravedimpression plate to provide a novel arrangement of means by which heatis applied thereto so that a wooden article held against said plate willhave the required impression made thereon.

-In the accompanying drawings, Figure 1 is a face view of an articleproduced by my improved mechanism. Fig. 2 is a face representation ofthe engraved plate for producing said article. Fig. 3 is a section ofthe engraved plate on dotted line a a Fig. 2. Fig. 1 is a perspectiveview of the press employed in connection with the mechanism. Fig. 5 is aplan view of the stationary bed 8 and plate 9, also the burners 14. Fig.6 is a vertical section through the bed 8 and plate 9 showing the burnerin position.

The press shown in Fig. 4: of the drawings comprises a well knownconstruction to which I have applied my improvements, and consists ofthe base 1 which supports the shaft 2 carrying the tight and loosepulleys 3 and at respectively. The large gears 5 are rotated by asuitable gear connection with the shaft 2. The platen 6 is pivotallyconnected with the base and is oscillated through the links 7eccentrically connected with the gears 5 and pivotally connected withthe platen.

The stationary bed 8 is supported by the base. To the bed 8 is secured aplate 9 by the bolts 10, and which is hold some distance therefrom bythe vertically arranged ribs 11 forming vertical fines 12. The bed 8 hashorizontal openings 13 through which burners 14: project. A gasolene orgas supply is furnished through the pipes 15 to the burners. Theseburners project into the vertical flues 12.

Specification of Letters Patent.

Application filed April 5, 1909.

Patented May 31, 1910.

Serial No. 488,151.

On the face of the plate 9 are located studs 16 and a movable finger 17An impression plate 18 is held in place by the studs 16 and finger 17and a wooden plaque 19 is held in place on the platen 6 by suitablegages. After the impression plate 18 is suitably heated, the press isset in motion which will move the platen and carry the wooden plaqueagainst the hot impression plate, thereby burning into the wooden plaquethe outlines on the impression plate as shown at Fig. 1.

The vertical flues 12 permit the proper draft to the heat furnished bythe burners, and said burners being centrally located, as said burnersbeing centrally located, as shown, the flame therefrom will be deflectedin opposite directions in the flues, when it strikes the rear wall ofthe heating plate.

By the employment of my improved apparatus, I am able to produce greatnumbers of plaques of burnt wood all the same, and the plaques can beused in the make up of boxes, or for wall ornaments.

I claim as my invention.

The combination with a bed having a series of centrally disposedtransverse openings therethrough, of a heating plate adapted to receivean impression plate and located in front of the bed in spaced relationthereto and extending across the openings, spacing ribs interposedbetween the bed and plate and extending between the openings, formingfines with which said openings communicate, and burners disposedtransversely to the bed and plate and having their front discharge endslocated in the openings and terminating short of the heating plate, saidends directing the heating medium against the rear face of the plate,and said plate causing the heating medium to be deflected in oppositedirections in the fines.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
